TYPE-SEGMENT FOR TYPE-WRITERS.

SPECIFICATION forming part of Letters Patent No. 380,372, dated April 3, 1888.

Application filed March 21, 1887. Serial No. 231,679. (No model.)

T0 asZZ whom it may concern-.-

Be it known that I, LOUIS T. Weiss, of Brooklyn, in the county of Kings and State of New York, have invented an Improvement in Type-Segments for Type-Vriters, of which the following is a specification.

Typewriters have heretofore been made in which segments containing types are made use of. In some cases three lines of types are contained in these segments, and sometimes there are two type-segmentsin one machine, swinging in opposite directions to the place where the impression is made. Reference is made to Letters Patent Nos. 290,419 and 290,420 for descriptions of machines making use of typesections of the general character before named.

In type-segments of this character the typefaces are usually of hard rubber fastened upon metallic arms, or else the type-segments and arms are all made of hard rubber. The surfaces of the types of hard rubber are not suffi ciently sharp and perfect to make perfectletters in printing, and the metallic type wheels or arms have been too heavy to be used advantageously,because of the inertiain starting and stopping the same.

My improvement is made to allow for using a metallic type segment possessing great strength, lightness, and durable sharp typefaces, and the metal frame that connects the same to the hub is very strong and without joints.

In the drawings, Figure 1 is a plan view, and Fig. 2 is a section in larger size,of atypewheel segment. Fig. 3 is an elevation, and Fig. 4 an end view, ofthe conical blank made use of in forming the segmental frame. Fig. 5 is a plan and Fig. 6 is an end view of the blank before the openings are cut in the same.

The type-segment A is of metal, preferably a hard quality of copperor bronze, formed by electro-deposit upon a proper matrix, and this type-segment is stiffened and strengthened by the rim 2 around it and by the deep V-shaped grooves between the lines of types, as seen at 3.

The hub O isprovided with the tubular axis D, the same as in aforesaid patent; but the connection between the type-segment and the hub is made of one piece of sheet metal, so as to be very strong and without seam.

A blank of conical shape is struck or spun up out of one piece of sheet metal, as shown in Figs. 3 and 4, and then it is bent into the shape shown in Figs. 5 and 6 by a suitable die and punch, so as to make a hollow frame, E, with diverging sides and with a segmental edge, and the sheet metal is cut or trim med by suitable dies, so that the outer edges fit within the rim 2 of the type-segment and the inner edges fit within the flanges of the hub C, and portions of the sides are cut away to form openwork to lighten the frame and leave hollow arms that are of the necessary strength, and the type-wheel segment is soldered to the outer edges of the hollow frame and the flanges of the hub are soldered to the inner portion of the hollow frame, as shown in Figs. 1 and 2. By this construction I am able to make a typesegment that is very strong and light, and hence will not become bent or injured by the momentum in the rapid stopping or starting.

At the end of the type-segmenta small strip of rubber or leatheris fastened, as at 6, to form a cushion to strike against the stationary stop usually found in machines of this class.

The type-segment may have the frame and hollow arms straight, or they may be more or less curved, as seen by dotted lines in Fig. 1, and there may be either one or two of my segments in each machine.

Any suitable solder or braze may be made use of.

I claim as my invention 1. The type-segment having a face of electro deposited metal, in combination with a hub and axis and a hollow frame of one piece of sheet metal without scam extending from the hub to the metal type-segment and soldered, substantially as set forth.

2. The type-segment having a rim projecting backwardly around its edge and V-channels between the lines of types, a hub, and a hollow sheet-metal frame extending from the hub to the type-segment and secured in place by solder, substantially as specified.

Signed by me this 15th day of March, A. D.
